Description

toothbrush

A kind of toothbrush, when the present invention especially refers to a kind of oral cavity cleaning, without manually adjusting or rotating the toothbrush body, the toothbrush that can clean the dead corner of the teeth that is more difficult to clean in the oral cavity smoothly.

The health of teeth has an inseparable relationship with the health of the whole body, so modern people pay more and more attention to the importance of "prevention is better than cure" to establish good oral hygiene and healthy teeth. Generally speaking, if the cleaning of the teeth is neglected, no matter how good the technology is to repair or wear dentures, it will not be comparable to natural teeth. Please refer to Fig . 1, the most important and most difficult position for brushing teeth is located between the curved surface under the contour ridge and the upper and lower areas of the gum line. (such as the buccal side, lingual side), and the lingual (inner side) area of the lower jaw is the most difficult to clean. [0004] Referring to Fig. 2, from an anatomical point of view, the dental arches of the upper and lower jaws are all curved. Just like a curved round arch is a stable structure, a curved dental arch is also an important reason why teeth of different shapes and functions can be stabilized in the same arc, and the current common dental arch types generally have narrow dental arches (narrow ), wide dental arch (square) and oval dental arch (oval), and various curved dental arches are stable, but for straight brush heads and necks, they are also one of the sources of interference in brushing. Please refer to Fig. 3 to Fig. 4, from the side view of the oral cavity dentition, there is a special and regular phenomenon, that is, the lower anterior teeth are high, and the lower posterior teeth are a slow or steep arc, the height of the two The drop forms a curve (speeˊs curve). The advantage of this curve is that when the teeth cut off, the posterior teeth do not touch, avoiding unnecessary contact and wear of the posterior teeth. This phenomenon causes the lingual side of the posterior teeth of the mandibular dentition to be The hardest hit area in the dead corner of oral cleaning. Because when the brush neck of the straight brush head is tilted according to the height difference, the direction of the brush head cannot be parallel to the dentition and the teeth, but is in an X-shaped cross state, that is, only a part of the bristles touch the teeth. Please refer to Fig . 5, the 3D three-dimensional environment formed by the teeth in the oral cavity and the upper and lower dentitions in the lingual (inner side) region of the mandibular posterior teeth has the following anatomical features, that is, the curved surface under the contour crest (as shown in the figure Horizontal arrow) is at an appropriate angle. When chewing, it can protect and self-clean the gums and teeth. But the fact is that after the food is ground and dissolved in the saliva, it will still be deposited on the teeth. A side effect of this protection is that the area under the contoured ridge becomes one of the dead spots for brushing. Please refer to Figure 10, the rear view of the oral dentition has another special rule, that is, the lower posterior teeth have a phenomenon of inclination to the lingual and palatal side, just like camping nails, when the posterior teeth are broken up and down and ground left and right When chewing, it provides a solid foundation that is not easy to shake. But it also makes it more difficult to brush the lingual side of the lower back teeth.

In view of above- mentioned problem, the present inventor has been engaged in the experience of relevant industry for many years, inspects the overall structure of toothbrush and user's habit; Therefore, the main purpose of the present invention is to provide a kind of auxiliary by toothbrush brushing neck, The toothbrush is a toothbrush that the user can use the brush head to clean the hard-to-clean tooth surface close to the tongue in the oral cavity without manually rotating or adjusting the toothbrush body.

[0010] In one embodiment, the first angle is between 12 degrees and 35 degrees, the second angle is between 45 degrees and -35 degrees, and the third angle is between 15 degrees and 85 degrees. [0011] In one embodiment, the end point of the second curved section close to the first curved section and the end point away from the first curved section form a height in a direction perpendicular to the first curved section, the height is between From 4mm to 15mm. [0012] In one embodiment, the first curved section is parallel to the arrangement direction of the 3rd to 7th teeth of the mandible. Through the above method, the brush head of the toothbrush of the present invention can avoid being disturbed by tooth inclination or other factors with the assistance of the brush neck, and help the user to smoothly clean the hard-to-clean oral cavity without manually adjusting the toothbrush body tooth dead ends.
